How to threshold an image
- Choose or drop an image. It opens with the Threshold style applied.
- Move Style amount to set the cut-off: lower keeps more white, higher keeps more black.
- Save as PNG from Export for crisp edges.
Good to know
- For signatures, threshold first, then use Remove a plain background to make the white transparent.
- Raise Contrast before thresholding for a cleaner split.
- Unlike Black and white, threshold keeps no grays at all.
Questions
What is the difference from black and white?
Black and white keeps every shade of gray. Threshold keeps only pure black and pure white.
Can I use it for stencils or laser cutting?
Yes. The result is a clean two-tone image you can trace or cut.
Why are there jagged edges?
Pure black and white has no in-between shades to smooth edges. Enlarging before thresholding gives smoother curves.
